Romanian national mapping of the continental platform

The coastal heights data combines two datasets: the land-sea mask of the gridded EMODnet bathymetry and the height of high-water (HAT) relative to chart datum (LAT) as computed with the GTSM tide model. Near the coast a diffusion scheme is applied to make the heights consistent with the land-sea mask. Finally, only grid cells that are classified as sea, but neighbor a land cell are selected. The main assumption in this approach is that the height of the topography near the coastline is close to the high-water mark. The main purpose of this dataset is to improve extrapolation towards the coast. In many areas around Europe there is a (small) gap between the point closest to the coast for which a survey is available and the coastline. In this way interpolation from coarser background data is avoided.

Gridded multibeam data acquired during scientific surveys and transits of French research vessels from 1992 to 2017 off the French Caribbean Islands.

DTM derived from a hydrographic survey (EMEPC LH1) performed within the scope of the Portuguese Continental Shelf Extension Project (UNCLOS). The data made available to the Emodnet project was sampled from the survey data with an aproximate 250m sampling interval, in N-S and E-W directions.

Source data for the EMODNet DTM for the Belgium Coastal Waters is compiled by the Vlaamse Hydrografie (http://www.afdelingkust.be/en/bathymetric-database) at a resolution of 1/512 arc minute. The data set covers the waters along the Belgian coast.
